🌧️ Why Rain is Good AND Bad for Wildfires ⚠️🔥
Rain plays a complicated role in fire season it can help firefighters, but it can also create new dangers for crews and communities. Here’s how:
✅ Why Rain is Good for Wildfires
1. Moistens Fuels – Raises moisture in grass, brush, trees, and duff, slowing fire spread.
2. Reduces Fire Intensity – Even light showers calm flames, giving crews time to build line and mop up.
3. Improves Air Quality – Rain knocks smoke out of the air, clearing skies and reducing health risks.
4. Supports Suppression Repair – Steady rain compacts soil on dozer lines and cools smoldering fuels.
⚠️ Why Rain is Bad for Wildfires
1. Flash Floods & Mudslides – Burn scars shed water fast, leading to floods and debris flows.
2. Soil Erosion – Hillsides wash away, clogging rivers and damaging roads.
3. Re-ignition Hazards – Light rain may only dampen the surface; hot stump holes can flare up again.
4. Firefighter & Community Safety Risks – Wet slopes, washed-out roads, and debris flows can trap crews and endanger nearby towns.
5. Infrastructure Damage – Sudden downpours erode firelines, wash out retardant berms, and damage pumps/hoses.
🚒 Bottom Line:
• Light, steady rain = good 🌧️🔥
• Heavy downpours on burn scars = dangerous for firefighters and communities 🌊⚠️
